Title: Method and apparatus for limiting high current electrical faults in distribution networks by use of superconducting excitation in transverse flux magnetic circuit
Inventor: KUZNETSOV STEPHEN B
IPC: H02H9/02
Filed: 1995-03-28
Abstract: The present invention pertains to an electrical fault limiter. The fault limiter comprises a first magnetic core.  There is also a second magnetic core opposing the first magnetic core. The fault limiter additionally comprises a third magnetic core adjacent the first magnetic core.  Also, there is a fourth magnetic core opposing the third magnetic core and adjacent the second magnetic  core.    The  electrical  fault  limiter  also  moreover comprises a rotor disposed between the first and second magnetic cores, and the third and fourth magnetic cores.   The rotor is rotatable about a rotor axis.  The first and second magnetic cores are disposed on a first side of the rotor axis and the third and fourth magnetic cores are disposed on a second side of the rotor axis.  Each core has a first arm, a second arm and a body to which the first and second arms  are connected.   Each body has  a superconduction bias coil disposed about it.   Each arm has a conduction mode coil disposed about it.   The rotor has a high magnetic reluctance sector and a return flux sector such that when the magnetomotive  force  from  each  superconduction bias  coil balances with the magnetomotive force from associated load coils on an associated core, there is no force on the rotor.  But, when the magnetomotive force from the superconduction bias coil is less than the  magnetomotive  force  from  associated  load  coils  on  the associated core, then a force is produced on the rotor causing it to accelerate.

Title: Zero superheat refrigeration
Inventor: POWELL JAMES W
IPC: F04D17/12
Filed: 1994-04-28
Abstract: A zero superheat refrigeration apparatus and method uses a multistage centrifugal compressor (4) which has a casing (10) with an axial inlet portion (8) at one end gaseously coupled to receive refrigerant from an evaporator (58), at two-stage motor driven compression portion (6), and an outlet opening (34) gaseously coupled to deliver compressed refrigerant to a condenser (52). An electric motor assembly (17) is within the inlet portion (8) of the casing (10) and includes vanes (12) to transfer heat dissipated by the motor assembly (17) to the refrigerant. The refrigerant cools the motor assembly (17) and the heat from the motor assembly (17) evaporates any liquid refrigerant droplets, allowing the evaporator (58) to operate at a zero superheat condition. A shaft (22), which is coaxially arranged in the casing (10), couples the motor assembly (17) to a first rotor (24) providing a first compression stage and to a second rotor (26) providing a second compression stage. The geometric shape of the casing (10) allows vehicle center line mounting.

Title: Wedge bar locking mechanism for burial casket
Inventor: LAJEUNESSE JOHN P
IPC: A61G17/02
Filed: 1995-11-07
Abstract: An improved wedge bar locking mechanism for a burial casket requires only a bracket, a screw and a clip which cooperate with one end of a wedge bar to cause longitudinal movement of the wedge bar in two directions for locking and unlocking the lid of a casket to the body of the casket.  The components of the mechanism are located in the body of the casket, adjacent an end wall. The bracket mounts rigidly to the body.  The screw threads directly to the wedge bar, and the bracket and clip hold opposite ends of the screw to prevent axial and radial movement thereof so that rotational movement of the screw is converted to longitudinal movement of the wedge bar.  The screw is accessible for rotation via a keyway in the end wall.  A center wall of the bracket engages the end of the wedge bar to prevent rotational movement thereof when the screw is rotated.  The bracket also includes integral tabs which serve as over-travel stops for both the locked and unlocked positions of the wedge bar.  This improved mechanism is less susceptible to failure than prior structures, and it requires fewer components, which translates to a cost savings due to reduced manufacturing and assembling expense.

Patent CA-2163932-A1 (CA)
Title: Method and apparatus for preventing the development of scale deposits in a water tank
Inventor: WOLFER PATRICK
IPC: B65D88/74
Filed: 1995-11-28
Abstract: Minerals such as limestone deposits are precipitated in tanks of steam generators, where drinking water is heated to produce steam. Such deposits can be only partially floated away by periodic opening of an elutrition or sludge-removal valve.          Since there is intensive crustation, the minerals stick on the heating members or the electrodes and sometimes cannot be removed because of their size through the waste water line. In the invention, one produces sufficient turbulence in the water by periodically blowing air through the water so that crustation is prevented and the accumulated sediments is separated in the form of powder of sludge to be treated by elutrition or sludge removal techniques.  The water tank 1 of the steam generator is equipped not only with a water feed line 5, a heating arrangement 2/3, an open steam outlet 1a and a sludge drain 6/7, but also with an air feed arrangement discharging into the base 1b or into the vicinity of the base of the tank. Such air feed arrangement is formed by an air pump 9 provided with a control device 9a and an air feed line 8.
